I'm using Synchron Strings I with VE PRO 6.0.17011 and VI Pro 2.4.16779 on macOS 10.12.6.
Say, I load 1st Violins MAIN . On all non soft patches, like Legato, Legato fast, Legato slur, Long I hear sforzando. In fact they are indistiguishable from the Sforzando patch. For comparison, the Special Edition patches behave as expected.
